Description of the Solution

Adds a new SVT theme, catalog_build, to the system test framework from #5711. It runs Omnia catalogs one after another on an OIM: for each catalog it s
elects the catalog (./omnia.sh --select-catalog), then runs the Repo Manager and Image Build Manager FVT steps (exec, then verify). The result is o
ne SVT report with one stage per catalog. The theme is defined as data in the same way as build_stream, and it uses the shared runner, readiness check
s, --retry / --start-stage and the HTML/JSON report, so it doesn't add a separate execution loop.

Changes

Theme definition (test/system_test/library/vars/)

• catalog_vars.py (new): reads the catalog plan written at configure time and builds one stage per catalog (catalog_01, catalog_02, ...), its title
  and its test cases, with IDs SVT_CATALOG_BUILD_<NN><SS>.
• theme_vars.py: registers the catalog_build theme (stages, soft stages, credential domains, cleanup and report settings), using the same fields as build_stream. force_rebuild defaults to true.
• test_case_vars.py: adds the generated catalog test cases to TEST_CASES.

Catalog runtime (test/system_test/library/functions/)

• catalog_settings.py (new): validates the catalog_build: block (catalog list, include_aarch64, repo_config, caching_policy, repo_policies, force_rebuild, continue_on_failure, cleanup_between, steps).
• catalog_func.py (new):
  • resolves catalogs: all or an ordered list against ./omnia.sh --list-catalogs, and skips aarch64 catalogs (with the reason) unless include_aarch6 4: true;
  • writes and checks reports/catalog_build_plan.json;
  • before each catalog, writes the run-wide repo_manager and image_build_manager settings into the runtime inputs, then selects the catalog;
  • runs cleanup_between (none, images, repos or full);
  • after a failed or timed-out step, stops orphaned ansible-playbook <domain>.yml workers and their child processes.

Shared framework hooks (opt-in; build_stream tests don't use them)

• test_func.py: optional test-case fields:
  • action: run an SVT action (catalog select or skip) instead of an FVT step;
  • always: run the test even after an earlier failure, used by cleanup_between;
  • stop_leftovers: clean up leftover playbook processes after a failed exec.
• fvt_func.py: SVT actions show as svt <action> ... in the report.
• config_func.py: loads and validates the catalog_build: block for the catalog theme.
• readiness_func.py: adds the initialization check "Catalog plan of this run (configure)".
• setup_func.py: makes bundled_catalogs() and select_catalog() public.
• _setup.py: --configure resolves the catalog plan and prints it; a plan error fails configure.
• svt_msgs.py: new CATALOG_MSGS.

Configuration and inputs

• catalog_build_test_config.yml (new): theme settings; ships with catalogs: all and gives an ordered list as a commented example.
• dataset_generator/profiles/catalog_build.yml (new): input profile for omnia.env, repo_manager and image_build_manager.

Documentation and tests

• docs/CATALOG_BUILD.md (new): user guide covering prerequisites, quick start, settings reference, reading the report, retry/resume and troubleshootin
  g.
• catalog_build_design.md (new): design of the theme on the merged SVT framework.
• README.md: catalog_build section and link to the guide.
• ut/test_catalog_build.py (new): unit tests for settings, the plan, generated stages and tests, readiness, the select/skip/cleanup actions, leftover-p
  rocess cleanup and the run_svt_test hooks.

Testing

• Unit tests: .venv/bin/python -m pytest ut -q gives 40 passed.

• Static checks:

  • pylint scores 10/10 on the new and changed code. The only warning is a too-many-locals warning in setup_func.py that was already there.
  • bandit reports no issues.

• build_stream regression: test collection is unchanged (13 build_stream tests, same stages and soft stages).

• End-to-end run on an OIM (RHEL 10.2, x86_64, run svt-20261112T061055Z), with an explicit two-catalog list:

  Stage	Catalog	Result	Duration
  initialization	-	Passed (7 checks)	0s
  catalog_01	rhel/10.2/slurm_x86_64_no_vast.json	17/17 passed	35m16s
  catalog_02	rhel/10.2/slurm_service_k8s_x86_64_no_vast.json	17/17 passed	~42m
  summary	-	Passed	1s

  Settings were repo_config: partial, caching_policy: true, force_rebuild: true, continue_on_failure: true and cleanup_between: none. run_vali dation.sh svt_catalog_build all exited 0, and the HTML/JSON report was generated with OVERALL STATUS: PASSED.

• Commands used:

  ./setup_env.sh --theme catalog_build
  ./setup_env.sh --theme catalog_build --status
  ./run_validation.sh svt_catalog_build list
  ./run_validation.sh svt_catalog_build all
  
  

• Not run:
• catalogs: all (every bundled catalog). It takes many hours; plan resolution and ordering for all are covered by unit tests.
• aarch64 catalogs ( include_aarch64: true ). No aarch64 build host was available.
• The GitLab pipeline generator for this theme isn't covered: it needs a configured run's plan file.

Backward Compatibility

• No breaking changes.
• The build_stream theme behaves exactly as before:
• the new test-case fields ( action , always , stop_leftovers ) are optional, and build_stream test cases don't set them;
• the catalog plan check runs only for catalog_build ;
• bundled_catalogs() / select_catalog() were only made public, with no change in behavior.
• No changes to user_inputs.yml , the src/ domain inputs or any FVT suite. The theme reuses the existing test/repo_manager and test/image_build_manag
er FVT runners.
• No migration needed. The new theme is opt-in via ./setup_env.sh --theme catalog_build .
